Choice B reason: Abdominal pain is not a sign of respiratory acidosis. It can be caused by other conditions such as gastritis, appendicitis, or gallstones.

Choice C reason: Dry skin is not a sign of respiratory acidosis. It can be caused by other conditions such as dehydration, eczema, or hypothyroidism.

Correct Answer is B

Explanation

Choice A reason: Spinach is a good source of potassium, but not the best. According to the USDA, one cup of cooked spinach contains 839 mg of potassium, which is about 18% of the recommended daily intake (RDI) for adults².

Choice B reason: Baked potato is the best source of potassium among the choices. According to the USDA, one medium baked potato with skin contains 941 mg of potassium, which is about 20% of the RDI for adults². Potassium is an essential mineral that helps regulate fluid balance, nerve and muscle function, and blood pressure.

Choice C reason: Banana is a popular source of potassium, but not the best. According to the USDA, one medium banana contains 422 mg of potassium, which is about 9% of the RDI for adults².

Choice D reason: Cheese is a poor source of potassium. According to the USDA, one ounce of cheddar cheese contains only 28 mg of potassium, which is less than 1% of the RDI for adults². Cheese is high in sodium, which can counteract the benefits of potassium and increase the risk of hypertension.

A. Respiratory rate 28/min B. Pink mucous membranes C. Heart rate 110/min D. Restlessness

Correct Answer is B

Explanation

Choice A reason: Respiratory rate 28/min is not a sign of effective oxygen therapy, as it indicates tachypnea, which is a rapid breathing rate. Tachypnea can be caused by hypoxia, anxiety, fever, or pain.

Choice B reason: Pink mucous membranes are a sign of effective oxygen therapy, as they indicate adequate oxygenation of the tissues. Pink mucous membranes are a normal finding, while pale, cyanotic, or jaundiced mucous membranes can indicate hypoxia or other problems.

Choice C reason: Heart rate 110/min is not a sign of effective oxygen therapy, as it indicates tachycardia, which is a rapid heart rate. Tachycardia can be caused by hypoxia, stress, dehydration, or infection.

Choice D reason: Restlessness is not a sign of effective oxygen therapy, as it indicates agitation, anxiety, or discomfort. Restlessness can be caused by hypoxia, pain, or medication side effects.
